How Do LED Grow Lights Work?

Based on experiments and studies, these special LED bulbs really work leafy plants, fruit-bearing plants, and flowering plants. In fact, NASA together with other different government agencies and universities already used these lights to grow indoor plants.

From hobbyists to professional indoor growers that run cultivation centers, these LED grow lights have already proved their worth. But just like any other piece of technology, you have to make sure that you know how to use it. Contrary to what other people think, indoor plants can still be harmed by too much artificial light.

Unlike us, plants have little tolerance when it comes to either insufficient or extra attention. Flash news, plants also need enough light at the right place with the right distance. But since indoor plants have limited options when it comes to location, it’s up to the LED grow light. These LED grow lights are constructed with small electronic components that are made from two different semiconductor materials. These materials work by creating their own light spectrum.

• First conductor – contains negative charges that are called electrons
• Second conductor – contains positive charges that are called holes

Once the voltage is applied, the electric current flows through it to make its holes and electrons collide. This process called recombination allows the bulb to release energy called photons or light quanta. The first versions of LEDs have a low light output and limited color options. But now, modern LEDs offer more color options and a higher level of brightness. Its types of lights also come in different types from visible, ultraviolet spectral, to infrared lights.

Unlike other bulbs, LED grow lights don’t use gas, mercury, and filaments to produce light. In addition, these lights that are more energy and cost-efficient tends to last longer than incandescent lights. Most importantly, LED grow lights are more eco-friendly, compared with any other kinds of lighting fixtures.

What Are the Benefits of Using LED Grow Lights?

Ever since LED bulbs were introduced in the market, their customer demand continues to increase over time. In fact, the majority of the bulbs and lighting fixtures that are sold on the market today are LEDs. Thus, even nature lovers nowadays who prefer to keep their plants indoors find ways to take advantage of these lights. So, these are the top benefits of having a good LED grow light:

• Energy-efficient

This is the number one advantage of LED grow lights to other lightings since LED bulbs consume fewer watts. However, it can produce the same light that High-Density Discharge (HID) bulbs have. Even with fewer bulbs, you can assure that the biggest portions of energy they use are converted into light than heat.

Unlike traditional lightings, LEDs don’t burn anything just to produce light. Thus, it wastes less energy which turns into heat while you can keep your energy bills at bay.

• Eco-friendly

As mentioned earlier, LED grow lights don’t contain mercury, gas, filaments, and any other toxic substances like HID lights. Instead, these light bulbs are designed and manufactured with eco-friendly materials that are 100% recyclable. Thus, you don’t have to worry about you or your plants getting harmed after being exposed to its light. To guarantee this, the best LED grow lights usually have a RoHS certification to prove its quality.

• Faster harvest cycle

Unlike outdoor plants that rely on the natural sunlight, indoor plants rely on artificial light from LEDs. These LED grow lights can be used for long hours to help your plants grow faster to increase your harvest cycle. Thus, you can regulate the red wavelength light at the right time to boost the growth of your plants.

You can also alter the daylight hours of these bulbs so you can have multiple harvests during one season.

• Healthier plants

Other artificial lightings release more UV rays, IR rays, and heat which harm the plants. But with LEDs, everything extra for the plants is reduced like the green and yellow wavelengths. Thus, your plants get just the right amount of these components which help them grow healthier and longer. In fact, you can also regulate the wavelengths of its lights which help your plants in the process of photosynthesis.

• Cooler operating temperature

Compared with HID lightings, LED grow lights produce less heat which doesn’t affect much the entire temperature indoors. This is especially true if you have a greenhouse where more LED lights are installed. Thus, you can cut costs for not needing a cooling system to keep your plants healthy.

How to Choose?

Now that LEDs are widely used by growers from different parts of the world, different versions arrive in the market. But instead of convincing you to buy from a single brand, we’ll let you decide on the product to buy. So, here are some tips and questions to answer so you can choose the LED grow lights:

• Look for chips

To make sure that your plants will grow, it has to have the right chips. In this case, the LED grow light that you should choose is the one with at least 3 watts. Any LED with less than 3 watts will not give your plants enough light coverage that can help them grow. Thus, every chip in the LED should have 3 watts since a 3 watts chip provides the best lighting solution.

You can notice this in blues, reds, and white LEDs so beware of those that only offer 1 watt each. Using 3 chips with 1 watt just to meet this requirement will not work either.

• Check the total output

Just like any other lighting solutions, you should also check its product description for the total output. Check the total number of units that the lamp has since it can also affect its produced amount of light. Some LED grow lights are built with 300, 400, 600, and even 1,000W. Before you head to the counter, check if it has at least 300W first. The higher the wattage the better since you can compensate for the loss of wattage over time.

• Consider its spectrum

Plants may grow under different kinds of light. However, it requires a specific amount of wavelength and spectrum to help them in photosynthesis. The best LEDs for growing indoor plants can provide a full spectrum that is necessary from their growth.

In this case, it should be able to provide enough amount of blues and reds as well as ultraviolet, and infrared. Depending on your plants’ stage of growth, their needed spectrum may also change to help them during the photosynthesis process.

• Look for its cooling aspects

Generally, LEDs produce less heat so a cooling system is not really necessary on some units. But since you’d be keeping these lamps on for more than 10 hours a day, you better check its cooling aspects. There are units with internal fans to protect the lamp from burning fast as well as your plants. The heat that comes out behind the bulbs should be protected with a cooling system to avoid burning its chips.

• Growing space

If LEDs vary in color, it also varies in size. Thus, be sure to measure the space you want to grow your plants to determine the exact size to buy. You also need to measure the lighting area to make sure that every plant you have is well-lighted. For high-light plants, you should have at least 32W/sq. ft. LEDs while low-light plants should have at least 11-18W/sq. ft.

• Ease of use

One of the most important things to look for when choosing an LED grow light is its ease of use. The best-LED lights for growing indoor plants should not give you a hard time while operating it. It should be flexible so you can adjust its lights depending on the kind of plant you have. At the same time, its growth stage should determine your LED’s placement.

Conclusion
